AWX: Dynamic inventory script using the value set in EXTRA_VARS

Get Help
1

I am trying to generate inventory data based on instance_id that will be given as a input as EXTRA_VARS

ansible-inventory -i inventory/my_inventory.py --list -e "instance_id=198"

url = https://api.myapp.com/id=<instance_id>
sample url: https://api.myapp.com/id=198

above URL shall give the list of hosts, using Dynamic inventory script
1a. get the instance_id from the EXTRA_VARS, in this case its instance_id and its value is 198
1b. query the url mentioned above
1c. Get the list of hosts
1d. build the inventory data in JSON

I am stuck at point (1a) above on how to get the instance_id into my Dynamic inventory script

how can I achieve this through dynamic inventory script? or please let me know any other way to achieve this

inventory scripts do not get extra vars, only inventory plugins can and they need to invoke a specific option for that
